2.5mm Fluorocarbon-Coated Bronze Textured Concave-Convex Aluminum Single Panel

The 2.5mm Fluorocarbon-Coated Antique Bronze Textured Concave-Convex Aluminum Veneer is a high-performance architectural decorative material. It is made of 2.5mm-thick aluminum alloy sheets (typically 3003 series, H24 temper) as the base material, formed into 3D concave-convex textures through CNC bending, molding, or etching processes, and finished with fluorocarbon spraying technology (incorporating a special antique bronze formula) for premium architectural applications.

Core Features & Advantages

1. Material Advantages

• Lightweight & High-Strength: Density of 2.7g/cm³, weighing only ~6.8kg/m², with tensile strength of 100-280N/mm². Reduces building load while ensuring structural stability.
•  
• Superior Weather Resistance: Fluorocarbon coating resists UV radiation, acid rain, and salt spray corrosion, maintaining colorfastness for 20-25 years outdoors.
•  
• Fire Safety: Non-combustible aluminum base meets global building fire safety standards.
•  
• Eco-Friendly & Recyclable: 100% recyclable, aligning with green building initiatives.
•  

2. Texture & Aesthetic Highlights

• 3D Layered Effect: Concave-convex textures create unique light and shadow interactions, enhancing the visual impact of building facades.
•  
• Antique Bronze Charm: Warm brown tones with metallic luster replicate the elegance of real copper at only 1/5 the cost.
•  
• Smooth Tactile Finish: Fluorocarbon coating offers a sleek, non-glare surface for comfortable visual experience.
•  

3. Craftsmanship & Performance

• Multi-Coat Protection: Adopts "three-coat two-bake" process (primer + antique bronze topcoat + clear coat) to form a composite protective film ≥40μm thick.
•  
• Extreme Environment Adaptability: Stable performance from -50℃ to 80℃ without deformation or discoloration.
•  
• Self-Cleaning Function: Low surface tension of fluorocarbon coating prevents dirt accumulation; rainwater rinsing restores cleanliness.

Manufacturing Process Details

1. Material Selection & Pre-Treatment
2. •  
     High-quality 3003/H24 aluminum alloy sheets undergo cleaning and chromate treatment to enhance coating adhesion.
   •  
3. Concave-Convex Forming (Optional Methods)
4. •  
     Die Stamping: Specialized molds create regular or irregular embossed textures.
   •  
   • CNC Bending: Precision CNC equipment bends sheets to form 3D geometric shapes.
   •  
   • Etching/Engraving: Chemical etching or mechanical engraving creates embossed effects with recessed patterns.
   •  
5. Surface Treatment
6. •  
     Primer: Epoxy primer for enhanced adhesion.
   •  
   • Antique Bronze Topcoat: Fluorocarbon paint with special metallic pigments to simulate copper color and texture.
   •  
   • Clear Coat: High-weather-resistant transparent coating for improved gloss and protection.
   •  
   • Curing: High-temperature baking at 230℃ ensures firm bonding between coating and base material.
